Explain the oxidation of primary, secondary and tertiary alcohols.
Prove that the relative depression of vapour pressure is equal to the mole fraction of solute.
An aromatic compound ‘A’ on treatment with $CHCl_3 / KOH$ gives two compounds ‘B’ and ‘C’. Both B and C give the same product ‘D’ when distilled with zinc dust. Oxidation of D gives E having molecular formula $C_7H_6O_2$. The sodium salt of E on heating with sodalime gives F which may also be obtained by distilling A with zinc dust. Identify A to F.
